CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 62/845,975 filed May 10, 2019, the entirety of which is incorporated by reference as if set forth in full below.

FIELD

This application generally relates to the alarm systems, methods, and devices, and, more particularly, to improvements to alarm systems for mapping and relaying real-time events, e.g., by transmitting real-time data from each sensor to mainframe controller.

BACKGROUND

National and local safety codes and regulations require public buildings, such as apartments and office buildings, to be provided with alarm systems (e.g., fire or smoke alarms) to alert occupants of certain dangers. In the related art, passive detection components are distributed around a building, and relate a signal to a single local control panel. The local control panel then sends a simple alert signal (i.e., merely an indication that there is an emergency) triggering emergency responders. Since these related systems include minimal if any intelligence, emergency responders must physically visit the site to determine whether the event is real or a false alarm, as well as the nature of the emergency, and the emergency location. This current model and method are very inefficient and ineffective.

For example, if a thermocouple sensor detects a temperature above a particular threshold, the thermocouple generates a signal to a local control panel indicating a sensor has detected excess heat. The local control panel then sends an alert to an emergency dispatch center, which dispatches firetruck(s), police, and ambulance(s) to the building. However, the signal does not provide information indicative of the temperature detected, nor the location within the building of the sensor, nor whether multiple sensors within the building have detected similar events, etc. Thus, emergency response personnel must attempt to ascertain this information manually upon arrival at the building, which delays response time and places everyone involved in danger

Thus, certain related art systems waste significant resources and valuable time in responding to emergencies, whether true or false. Moreover, without real-time mapping of emergency events, danger to property and individuals is increased because much of the response is driven by guesswork.

Accordingly, what is needed are improved alarm system, methods, and devices. Aspects of the present disclosure address these and other issues.

DETAILED DESCRIPTION

The following detailed description illustrates the invention by way of example and not by way of limitation. This description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what we presently believe is the best mode of carrying out aspects of the invention. As various changes could be made in the above constructions without departing from the scope of the disclosure, it is intended that all matter contained herein or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Certain embodiments of the present disclosure includes systems for monitoring the presence of events in a building and transmitting this information to a remote emergency dispatch center. The system may include a plurality of smart sensors located at predetermined locations within a building. The sensors monitor one or more conditions, such as temperature, smoke, noise, air quality, and the like. The sensors may also capture and/or record sound or video. The smart sensors may transmit information associated with monitored condition(s) (e.g., temperature, CO₂ level). In addition, the smart sensor may transmit an indication of a location of the sensor (e.g., location description, sensor identifier (ID), floor number, or the like). In some cases, the smart sensors may transmit this information to a local monitoring station (e.g., a central workstation located at or near the building), which is in communication with each of the plurality of smart sensors. When an event is detected, the smart sensors may monitor (e.g., continuously or repeatedly) the conditions and update the local monitoring station as to any changes to the conditions. The local monitoring station may analyze data from the plurality of smart sensors to determine event location, status, and type. For example, by continuously monitoring a plurality of smart sensors, the local monitoring station may detect a fire and determine the fire's location, intensity (e.g., temperature), and movement direction. With this information, emergency response personnel may be better equipped to respond to the event.

In some embodiments, the local monitoring station may compile the information, and compose, in real-time, a map (e.g., a 3-D) of the event based on the sensor data. The real-time 3D image can be transmitted to first responders (e.g., to a remote monitoring station (“RMS”) or via a tablet or other internet-connected device). Additionally, by monitoring the plurality of smart sensors, the local monitoring station may determine false alarms, and turn off system responses (e.g., sprinklers). For example, if a heat detector is triggered by an impact, it may still transmit expected (room) temperature readings. Further, additional heat detector(s) near the impacted heat detector may continue indicating standard temperatures. Alternatively, in some cases, triggering the heat detector may automatically turn on a camera, which can capture images of the area near the heat detector. By analyzing data from one or more of the impacted heat sensor, the nearby other heat detectors, and/or image data from the camera, the local monitoring system may determine that the event is a false alarm.

In certain implementations, each smart sensor may be connected to the local monitoring system through a combination power-data line. Accordingly, unlike in related art systems where each smart sensor requires its own backup battery, a universal backup battery may be centrally located at the local monitoring system, which may provide power to any of the sensors as needed. Furthermore, the local monitoring system may track power sent from the battery to identify sensors without standard power, and trigger an alert to perform sensor maintenance. Likewise, if a smart sensor unexpectedly ceases sending data to the local monitoring system (e.g., an update of the condition status every 30 seconds) or the condition readings become unintelligible (e.g., a heat detector not being triggered at very high heat), the local monitoring system may send an alert for sensor maintenance.

Although a local monitoring station is generally described as receiving all sensor data, this is merely an example. In some cases, the sensors may individually include transceivers. In some cases, the sensors may form a mesh network, and may transmit their information to edge sensors (e.g., sensors nearest a window or whose transceivers otherwise have a best data connection), and may transmit their information to a remote monitoring station.

According to some embodiments, the smart sensors may automate location setting. For example, a plurality sensors may communicate with each other to triangulate their respective locations within a building. For instance, if a first sensor is known to be on a northeast corner of a given floor of the building, adjacent sensors may determine their locations based on, for example, signal strength and direction. In some cases, the sensors may output directional signals (e.g., coordinated directional signals), such that each sensor may more accurately determine its relative location to the remaining sensors.

Reference will now be made the figures in which aspects of the present disclosure are illustrated.

FIG. 1 is a flow diagram 100 of an emergency alert flow a monitoring system in the related art. In FIG. 1, a plurality of sensors are distributed across a building. Each sensor is connected to a local control panel in the building. When a sensor detects 110 an event (e.g., smoke), it sends 1120 a signal to the local control panel. The local control panel then alerts 130 emergency responders that an event has occurred in the building. However, the sensors and local control panel are unable to determine or relay the type of event, where the event occurred, a size of the event (e.g., whether multiple sensors were triggered, or a current status of the event. Responders, therefore, must arrive 140 onsite, access 150 the local control panel, find 160 the triggered sensor, and 170 address the event.

FIG. 2 is a diagram 200 of an emergency sensor system installed in a building according to an example embodiment. FIG. 2 illustrates the system including a plurality of smart sensors 210 distributed in various rooms on a floor of the building. One of ordinary skill will recognize that additional floors may have one or more smart sensors 210 distributed therein, either in similar or different configurations. Each of the smart sensors 210 is connected to a local monitoring station (“LMS”) 220. In some cases, the connection may be a bi-directional information channel. In some cases, the connection may by two-wire ethernet, DSL, and/or a wireless connection.

In the related art, individual sensors require individual battery packs for backup. When a sensor loses main power, the battery is used and drained. Until the battery gets low, there is no indication that the sensor does not have a primary battery source. In contrast, in some implementations, the connection to LMS 220 may be configured to provide backup power to smart sensors 210. When smart sensor 210 requires backup power, LMS 220 may provide the same from a central battery backup and/or an alternative main power source (e.g., LMS 220's main power source). LMS 220 may monitor power consumption of the smart sensors 210 to determine when the sensors 210's main power source is unavailable and output an alert for sensor maintenance.

Smart sensors 210 may detect one or more conditions, and update LMS 220 of the condition status. The update may include, sensor information and/or ranges (e.g., indicating a temperature. Fire intensity, smoke particles per million), and may include either location (e.g., floor, room and/or location reference) or a sensor ID (e.g., if LMS 220 know the location). For example, smart sensors 210 may detect fire, smoke, carbon monoxide, motion, temperature, carbon dioxide, light, and/or humidity.

When an alert is triggered by one or more smart sensors 210, LMS 220 may analyze the sensor data and location information to map out the event in real-time. For example, LMS 220 may generate a real-time event map, such as by overlaying the sensor data (or representations of the sensor data) on a floorplan. In some cases, smart sensors 210 may include a camera and/microphone. Images and/or sounds from the sensors may be included in the real-time event map. In some cases, the camera and/or microphone may only be activated by a signal from LMS 220.

In some cases, a building may be retrofitted to include one or more smart sensors 210 and LMS 220. For example, in some cases, a building may have traditional sensors that draw power using traditional power lines (e.g., copper wires). The traditional sensors may be replaced with smart sensors 210 and the local control panel may be replaced with LMS 220. The smart sensors 210 may connect to LMS 220 through the power lines. LMS 220 may provide power to the smart sensors 210 through the power lines and/or communicate with the smart sensors 210 via ethernet-over-power. In some cases, DSL lines may run to the traditional sensors, and the smart sensors 210 may communicate with LMS 220 through a DSL connection.

FIGS. 3A and 3B illustrate a real-time map according to an example embodiment. Referring to FIG. 3A, there is provided a layout of a floor including sensor locations. The condition statuses sensed by the various sensors are presented. For example, a first smart sensor 210 detected a fire and extinguisher in its room. These may be represented by, for example, icons 305 and 310, respectively. A second sensor 210 in an adjacent room detects elevated temperatures and smoke. These conditions are represented by icons 315 and 320, respectively. Similarly, sensors 210 located farther from the fire may detect smoke by no elevated temperature, while a sensor 210 in an adjacent room without a passage may detect elevated temperatures by no smoke. A value or intensity of the detection may be communicated by, for example, a size of the respective icons, a color of the icons, or through some other indicator.

The real-time map may be updated as matters change. For example, in FIG. 3B, the fire has spread, and smoke, heat, fire, and sprinklers are now detected in by additional sensors. Additionally, the fire has damaged the sensor in the first room, and is no longer providing sensor data. Therefore, a most recent known status is shown faded out. The real-time map updates may be saved and the event (e.g., spreading of a fire) may be replayed later for investigative purposes.

In certain implementations, LMS 220 may poll smart sensors 210 for a condition status regularly (e.g., through a two-way data connection). For example, if a smart sensor 210 has not submitted a condition status within a predetermined period of time, LMS 220 may initialize communication with the smart sensor 210. If no response is given (or the response is erroneous or otherwise unintelligible), LMS 220 may output an alert indicating that sensor maintenance is needed.

FIG. 4 is a flow diagram 400 of an emergency alert flow of a monitoring system in according to an example embodiment. In FIG. 4, a plurality of smart sensors 210 are distributed across a building. Each sensor 210 is connected to the LMS 220. When a sensor 210 detects 410 an event (e.g., smoke), it sends 420 a signal to the LMS 220 along with condition information. LMS 220 gathers 430 condition information from a plurality of sensors 220 and alerts responders. Before responders arrive, LMS provides 440 a real-time map of the event based on sensor data from the sensors 220. Thus, when responders arrive on scene, they proceed 450 directly to the event location and address the event.

FIG. 5 is a block diagram of an illustrative computer system architecture 500, according to an example implementation. As non-limiting examples, aspects of smart sensors 210 and/or LMS 220 may be implemented using one or more elements from the computer system architecture 500. It will be understood that the computing device architecture 500 is provided for example purposes only and does not limit the scope of the various implementations of the present disclosed systems, methods, and computer-readable mediums.

The computing device architecture 500 of FIG. 5 includes a central processing unit (CPU) 502, where computer instructions are processed, and a display interface 504 that acts as a communication interface and provides functions for rendering video, graphics, images, and texts on the display. In certain example implementations of the disclosed technology, the display interface 504 may be directly connected to a local display, such as a touch-screen display associated with a mobile computing device. In another example implementation, the display interface 504 may be configured for providing data, images, and other information for an external/remote display 550 that is not necessarily physically connected to the mobile computing device. For example, a desktop monitor may be used for mirroring graphics and other information that is presented on a mobile computing device. In certain example implementations, the display interface 504 may wirelessly communicate, for example, via a Wi-Fi channel or other available network connection interface 512 to the external/remote display 550.

In an example implementation, the network connection interface 512 may be configured as a communication interface and may provide functions for rendering video, graphics, images, text, other information, or any combination thereof on the display. In one example, a communication interface may include a serial port, a parallel port, a general-purpose input and output (GPIO) port, a game port, a universal serial bus (USB), a micro-USB port, a high definition multimedia (HDMI) port, a video port, an audio port, a Bluetooth port, a near-field communication (NFC) port, another like communication interface, or any combination thereof. In one example, the display interface 504 may be operatively coupled to a local display, such as a touch-screen display associated with a mobile device. In another example, the display interface 504 may be configured to provide video, graphics, images, text, other information, or any combination thereof for an external/remote display 550 that is not necessarily connected to the mobile computing device. In one example, a desktop monitor may be used for mirroring or extending graphical information that may be presented on a mobile device. In another example, the display interface 504 may wirelessly communicate, for example, via the network connection interface 512, such as a Wi-Fi transceiver to the external/remote display 550.

The computing device architecture 500 may include a keyboard interface 506 that provides a communication interface to a keyboard. In one example implementation, the computing device architecture 500 may include a presence-sensitive display interface 508 for connecting to a presence-sensitive display 507. According to certain example implementations of the disclosed technology, the presence-sensitive display interface 508 may provide a communication interface to various devices such as a pointing device, a touch screen, a depth camera, etc. which may or may not be associated with a display.

The computing device architecture 500 may be configured to use an input device via one or more of input/output interfaces (for example, the keyboard interface 506, the display interface 504, the presence-sensitive display interface 508, network connection interface 512, camera interface 514, sound interface 516, etc.) to allow a user to capture information into the computing device architecture 500. The input device may include a mouse, a trackball, a directional pad, a trackpad, a touch-verified trackpad, a presence-sensitive trackpad, a presence-sensitive display, a scroll wheel, a digital camera, a digital video camera, a web camera, a microphone, a sensor, a smartcard, and the like. Additionally, the input device may be integrated with the computing device architecture 500 or may be a separate device. For example, the input device may be an accelerometer, a magnetometer, a digital camera, a microphone, and an optical sensor.

Example implementations of the computing device architecture 500 may include an antenna interface 510 that provides a communication interface to an antenna, a network connection interface 512 that provides a communication interface to a network. As mentioned above, the display interface 504 may be in communication with the network connection interface 512, for example, to provide information for display on a remote display that is not directly connected or attached to the system. In certain implementations, a camera interface 514 is provided that acts as a communication interface and provides functions for capturing digital images from a camera. In certain implementations, a sound interface 516 is provided as a communication interface for converting sound into electrical signals using a microphone and for converting electrical signals into sound using a speaker. According to example implementations, a random-access memory (RAM) 518 is provided, where computer instructions and data may be stored in a volatile memory device for processing by the CPU 502.

According to an example implementation, the computing device architecture 500 includes a read-only memory (ROM) 520 where invariant low-level system code or data for basic system functions such as basic input and output (I/O), startup, or reception of keystrokes from a keyboard are stored in a non-volatile memory device. According to an example implementation, the computing device architecture 500 includes a storage medium 522 or other suitable type of memory (e.g. such as RAM, ROM, programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), magnetic disks, optical disks, floppy disks, hard disks, removable cartridges, flash drives), where the files include an operating system 524, application programs 526 (including, for example, a web browser application, a widget or gadget engine, and or other applications, as necessary) and data files 528 are stored. According to an example implementation, the computing device architecture 500 includes a power source 530 that provides an appropriate alternating current (AC) or direct current (DC) to power components.

According to an example implementation, the computing device architecture 500 includes a telephony subsystem 532 that allows the device 500 to transmit and receive sound over a telephone network. The constituent devices and the CPU 502 communicate with each other over a bus 534.

According to an example implementation, the CPU 502 has appropriate structure to be a computer processor. In one arrangement, the CPU 502 may include more than one processing unit. The RAM 518 interfaces with the computer bus 534 to provide quick RAM storage to the CPU 502 during the execution of software programs such as the operating system application programs, and device drivers. More specifically, the CPU 502 loads computer-executable process steps from the storage medium 522 or other media into a field of the RAM 518 to execute software programs. Data may be stored in the RAM 518, where the data may be accessed by the computer CPU 502 during execution.

The storage medium 522 itself may include a number of physical drive units, such as a redundant array of independent disks (RAID), a floppy disk drive, a flash memory, a USB flash drive, an external hard disk drive, thumb drive, pen drive, key drive, a High-Density Digital Versatile Disc (HD-DVD) optical disc drive, an internal hard disk drive, a Blu-Ray optical disc drive, or a Holographic Digital Data Storage (HDDS) optical disc drive, an external mini-dual in-line memory module (DIMM) synchronous dynamic random access memory (SDRAM), or an external micro-DIMM SDRAM. Such computer readable storage media allow a computing device to access computer-executable process steps, application programs and the like, stored on removable and non-removable memory media, to off-load data from the device or to upload data onto the device. A computer program product, such as one utilizing a communication system may be tangibly embodied in storage medium 522, which may include a machine-readable storage medium.

In example implementations of the disclosed technology, a computing device may include any number of hardware and/or software applications that are executed to facilitate any of the operations. In example implementations, one or more I/O interfaces may facilitate communication between the computing device and one or more input/output devices. For example, a universal serial bus port, a serial port, a disk drive, a CD-ROM drive, and/or one or more user interface devices, such as a display, keyboard, keypad, mouse, control panel, touch screen display, microphone, etc., may facilitate user interaction with the computing device.
